True because the Hypertonic solution, all three of the cells let the water out and became smaller in size almost looking like they were shrinking or shriveling up.
Answer:
True
Explanation:
Phospholipids have both hydrophobic and hydrophilic regions in a single molecule. The phosphate head group is hydrophilic because it is polar, enabling it to form hydrogen bonds with water.
Answer:
The cytoplasm of an unfertilized egg contains cytoplasmic determinants that decide the fate of epidermal, endodermal and muscle cells.
Explanation:
- The ovum or egg is the largest cell in the human body. It contains a large amount of nutrients and substances required for protein synthesis and growth of the embryo.
- An unfertilized egg contains a mixture of mRNA and proteins that act as cytoplasmic determinants. Cytoplasmic determinants are molecules that regulate gene expression. In an ovum, they decide which part of the fertilized egg will eventually develop into which tissue.
- Along with cytoplasmic determinants, the cytoplasm of an unfertilized egg contains large amounts of nutrients and mitochondria to provide maximum energy during embryonic division and growth.
Water is very important Marina living organisms maintained
Answer:
B. Cells
Explanation:
The plasma membrane is one of the essential structural and functional components of all the cells. It maintains the cell's interior and regulates the entry and exit of substances into and out of the cells. Both prokaryotic and eukaryotic cells have a plasma membrane.
Plasma membrane forms the outer most covering of an animal cell. Plant cells and bacterial cells have a cell wall outside the plasma membrane. Irrespective of the cell type, the plasma membrane is made up of a bilayer of phospholipids with a hydrophobic core. Several proteins are embedded in the lipid bilayer.
